Abstract

BackgroundMusculoskeletal pain MSP is a commonly reported symptom in youth sports players. Some sports-related risk factors have been reported, but previous studies on extrinsic risk factors did not focus on management of team members e.g., regular or non-regular players, number of players for reducing sports-related MSP. This study aimed to examine the association of playing status regular or non-regular players and team status fewer or more teammates with MSP in youth team sports.

MethodsA total of 632 team sports players age: 12–18 years in public schools in Unnan, Japan completed a self-administered questionnaire to determine MSP overall, upper limbs, lower back, and lower limbs and playing status regular or non-regular players. Team status was calculated as follows: teammate quantity index TQI = number of teammates in their grade-required number of players for the sport. Associations between the prevalence of pain and joint categories of playing and team status were examined by multivariable-adjusted Poisson regression.

ResultsA total of 272 44.3% participants had MSP at least several times a week in at least one part of the body. When divided by playing or team status, 140 47.0% regular and 130 41.7% non-regular players had MSP, whereas 142 47.0% players with fewer teammates lower TQI and 127 41.8% players with more teammates higher TQI had MSP. When analyzed jointly, regular players with fewer teammates had a higher prevalence of lower back pain compared with non-regular players with more teammates 21.3% vs 8.3%; prevalence ratio = 2.08 95% confidence interval 1.07–4.02. The prevalence of MSP was highest in regular players with fewer teammates for all other pain outcomes, but this was not significant.

ConclusionRegular players with fewer teammates have a higher risk of lower back pain. Future longitudinal investigations are required.
